FORMATION OF AN ARTICLE AND ITS APPLICATION TO ANOTHER ARTICLE.

Specification of Letters Patent.

Patented J an. 10, 1911.

Application filed March 18, 1908, Serial No. 421,962. Renewed May 31,1910. Serial No. 564,139.

To all whom it may concern:

Be it known that I, ROBERT KRoEoEL, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in the Formation of an Article and Its Application toAnother Article; and I do hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification, and to thereference-numerals marked thereon.

The present invention which relates to the formation of an article andthe application thereof to another article, such for instance asstifi'ening strips for the bellows for cameras and the like, has for anobject to simplify the manufacture of articles of this type and tosecure greater accuracy in the positioning of the formed article on theother.

To these and other ends the invention consists in certain improvementsand combina; tions of parts all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawings: Figure 1 is a front view of a machine for applyingstiffening strips to the linings of camera bellows, embodying thisinvention. Fig. 2 is a vertical cross section of the same machine. Fig.3 is a top view of a male die which is employed for forming the strips,surrounding portions of the machine being also shown. Fig; 4 is a planview of the same machine. Fig. "5 is a. vertical section through afemale die employed in this machine. Fig. 6 is a lan view of a portionof the female die. Flg. 7 is a vertical section through the male diebefore mentioned; and Figs. 8 and 9 are plan views of two side walls ofa camera lining after the stifiening strips are aplie 1 P Bellowsmanufactured from linings made in accordance with this inventioncomprise an outer casing, a lining, and stiffening strips spaced aparton all sides between the lining and the casing, the completed articlebeing folded or bent between the strips. If these strips be laid by handthey must be applied one by one and this operation not only consumes agreat amount of time, which makes the cost of manufacture expensive, butthe bellows when completed, are not neat owing to the inaccuratepositioning of the stiffening strips. In the present invention, all thestiffening strips for each side are formed in the relation which theyare to have on the lining and are applied directly to the latter fromthe forming mechanism, so that not only is the time consumed in applyingthe strips lessened, but greater accuracy is secured.

The forming mechanism in the present instance comprises a male die and afemale die, which are relatively movable. The male die is preferably inthe form of a plurality of spaced knives 1 arranged parallel to eachother and having the form of the strips to be out, which are illustratedin Figs. 8 and 9, where they are arranged on a lining, and it will benoted that ever other strip is narrow as compared with t e others andthat; they gradually decrease in length toward, one end of the lining.The knives 1 areksecured to a base plunger 2, which for this purpose isprovided with seats for the knives. Plates 3 arranged at opposite endsof ,the knives are secured by fasteners 4: to the plunger and fitrecesses 5 in the ends of the knives to hold the latter in their seats.A stripper in the form of a slotted plate 28 fits over the knives 1 andnormally lies with itsupper face inthe plane of the upper faces of theknives. It is supported in this position by springs 29 which surroundguide rods 30 that work in ways 31 in the plunger 2,'the rods working inopenings in plates 3 and being formed with enlargements 82 to engage theunder surfaces of the said plates 3 in order to limit the upwardmovement of thev stripper.

The plun er 2 is guided on rods 6 depend ing from t e frame of themachine and works in a fluid cylinder 7 which is suspended bythe rods.Fluid admitted through pipe 8 to the cylinder 7 moves the piston and themale die to the fe1nale die.

The upwardmovement of the inale die is limited by adjustable stops 34which are carried by rods 35 depending fror'nthe plunger 2 and engagingbeneath the plate 36 that serves to support cylinder 7. The female die.is formed with a plurality of slots 9 corresponding in cross section tothat of the male die so as to receive the" latter and to permit it topass therethrough. It is preferably formed by a base plate 10 resting onthe frame 11 and having a continuous opening 12 formed therein. Onopposite sides of the opening are formed seats 13 for ribs 14 that areprovided on the under surface of a pair of plates 17 secured to the topof the base plate 10, by screws 18, the ends of the ribs on theproximate sides of the plates being projected and having their extremeedges forming knives to shape the ends of the strips. Resting at theirends on the seats 13 across the opening in the base plate and betweenthe ribs 14 is a series of knives 15 which form the sides of the strips.The proximate sides of the plates 17 form a pocket or guide 19 toreceive the supported lining. A lining 20 fitted about a support 21, isheld in the pocket or guide by a hold ing means comprising in thisinstance a swinging frame 22 carrying a yieldingly mounted plate 23 toengage the supported lining and pivoted at 24: to brackets'25. At itsswinging end the frame carries a handle 26 by which it is operated, andit is engaged by a pair of latches 27 preferably pivoted to the plate 17and moved in the direction to engage automatically frame 22 when thelatter is moved to them, by means of spring pressed lunger 27 I Inoperation tlie lining 20 is fastened tightly over the support 21 and isthen moistened and dropped over the pocket 19 with one side in contactwith the upper side of the female die. A sheet of material is laid onstripper plate 28 with its gummed face uppermost and then the plunger 2is moved to elevate the sheet with the male die. hen the latter reachesthe female die its knives cooperate with theedges of the walls of theslots and all the strips for one side of the bellows are formed in therelation which they are to hold on the bellows. After the cutting of thestrips the female die acts as a guide for the strips to direct them tothe lining. Of course, while the strips are being cut, and directed tothe lining, the stripper plate yields downwardly because of itsengagement with the female die and when the male die is withdrawn, the

stripper removes the perforated sheet from labor. ture 1s reduced verymaterially and greaterv the knives. The lining with its support is nowturned and its opposite face is presented to the female die to receivestrips in the same manner. The other two sides which receive strips likethose shown in Fig. 8,.

have the strips applied in a separate machine with dies formed tocorrespond therewith.

The machine herein shown is inexpensive to manufacture and its simpleoperation permits of its being controlled by unskilled The time consumedin the manufac- -ne atness and accuracy, with less waste, is

secured.
